摘要

本研究报告了掺杂纳米级镍的蒙脱石杂化催化剂的合成和表征及其在芳基碘化物与芳基硼酸的铃木宫浦交叉偶联中的应用。该催化剂具有高选择性,不会产生任何其他副产品。反应在 24 小时内完成,产率达 98%。镍均匀地分散在催化剂上,镍团约为 4.0 ± 2 nm。通过改变溶剂、碱、催化剂负载量和催化剂前驱体,获得最佳反应条件,从而获得最高产率。催化剂回收后可重复用于反应,这表明催化剂具有极佳的可回收性和高产率。掺杂镍的蒙脱石催化剂对铃木宫浦交叉偶联反应非常有效,可以用地球上丰富而廉价的镍基催化剂取代昂贵的钯基催化剂。

Nanosized-Ni Doped on Montmorillonite Catalysed Suzuki–Miyaura Coupling Reactions

This work reports the synthesis and characterization of Nanosized-Ni doped montmorillonite heterocatalyst and its application for Suzuki Miyaura cross coupling of aryl iodides with aryl boronic acids. The catalyst is highly selective and did not give any other byproducts. The reaction was complete within 24 h with > 98% yield. Nickel was uniformly dispersed on the catalyst with approximately 4.0 ± 2 nm clusters of Ni. The solvent, base, catalyst loading, and catalyst precursors were varied to obtain optimum reaction conditions for highest yield. The catalyst was recovered and reused for reactions demonstrating excellent recyclability with high yield. Ni doped montmorillonite catalyst is very effective for Suzuki Miyaura cross coupling reactions and can be used to replace expensive Pd-based catalysts with earth abundant and inexpensive Ni-based catalysts.

期刊介绍: Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
